The Jemmy crack corn DAC is probably good but no way is going to compete with Creamy Custard stock and has way less potential to mod. Only one DAC and the power transformers are tiny widdle bitty thangs (5 Watt each). The tranformers in the Custard are at least 50 watters......look even bigger than that. The bigger the tranny the better the sound. And power connector cables with connectors will mess up the sound as well.
I will be doing a second level of baby mods to the Custard tomorrow (twisting AC wires, WA quantum dots, shorting out unused digital inputs and damping a couple of parts). Early next week I will remove the entire output stage and get serious. I will post pics of the mods as I go. The baby mods anyone can do themselves. So far, the first two mods (eliminate fuse and bolts on trannies) have taken the DAC to another whole level of reality......Guys, you must do these mods! Costs you next to nothing!
